Dont open the ps3 by yourself. you will only void the warranty and you may mess up something. Best thing to do is take it to a sony service center in your area and they will get it fixed within 10 minutes. If there isnt a sony service center in your area then take it to some game store who have got experience in doing this job. If there isnt anyone who fix it then do it by yourself but be very careful. Make sure you dont damage the blu ray laser.
